belt drive noise ??

#1

Post by neilw » Thu Apr 19, 2012 7:43 am

A week or so I mentioned ( or maybe read another post ) a belt drive for my 59 pan. I dont like the idea of oil splattered on my whitewall tire. I was informed that belt drives make a lot of noise, of coarse the chain does too, but its a Harley noise . I see several belt drives in the $275.00 range ,are any of these quiet? Or can you do something to quiet them down?
Thanks , Neil

Are you asking about a rear belt drive for your '59? I've not ever seen that done. Not saying it's not possible, it's just something that I've not seen. Sounds like a pretty complex conversion--- not even sure it's possible.
And if you're talking about a belt primary drive, you're still going to have oil on the rear chain. A chain needs oil, anyway, or it won't last very long.

With my Non-stock cam gear I can't hear any belt noise (just a loud "whine" from the gear case)!

I went with a belt for several reasons....

1. After 32 years of Rust and Being Moved Several Times I was missing some primary drive parts.

2. The Belt Was CHEEP'er (like me).

3. I've learned to Hate a Damn Chain after 40 years on different bikes.

Honestly, I can't say any of mine are noisy. (The Pan in a closed primary and a 3" BDL on a Evo Bob, open primary.)

Go ahead and throw a brick about can't repair a belt with a Repair Link.

I'm running an ancient Primo belt primary on my '41 pan (or is it a '59 knuck..?!), I installed it sometime around 1975. It's always been whisper quiet...! (And about due for replacement now...)

Open primaries are noisy, whether belt or chain. Enclosed belts are far quieter than any chain drive ever hoped to be. A 1-1/2 inch belt within tin primaries will make you notice all the other little noises your engine makes that the chain drive hid from you!

I like the BDL 1 1/2 inch belt in my closed primary on my 51. A lot quieter than the chain, and a lot less work.
I have not had to adjust it since new 8000+ miles ago. Even had some oil on it from an over filled tranny.

The only noise I ever noticed wasn't coming from the belt drive but from the chatter of the clutch plates inside the clutch shell. The belt moving over the pullies is WAY more quiet then a primary chain.

Robbie, Great Picture, and and probably the best looking Knuck bagger I've ever seen! Great to see an old bike that travels as good as it looks.

JR,
When I first built it I thought I might hang a sidecar on it which never happened. I built it with a 22 on the trans. It is a very smooth, quiet, and nice running bike. I live at 7000 ft and ride a lot in the mountains. It is quite happy at a constant 60-65 and will easily run 85-90 with no issues and little vibration loaded as in the picture. It has alloy pushrods and collars, an older Andrews cam, points ignition, 32E genny and solid state relay, belt primary, stock oil system, M74B carb.
